'14 Claims. 1

This invention relates to improvements in tabulators and has particular reference to a change of designation control therefor, this application being a division of my co-pending application Serial No. 13,017, filed March 4, 1948.

An object of the invention is to utilize, in an improved manner, sensing and analyzing stations each having mechanisms thereat in which cards are compared and from which a controlled element is differentially actuated, by the likeness or dissimilarity in designation between cards at the twostations, to control the continuation of the card feed or the stopping thereof and initiation of a" total-taking cycle.

The above and other objects will appear more clearly from the following detailed description when taken in connection with the accompanying drawings; but it is to be expressly understood that the illustration in said drawings is employed merely to facilitate the description of the inven tion as a whole and not to define the limits thereof, reference being had to the appended claims for this purpose.

n ral y. t e tab lator compr s s a supp rting base 30 from which extend upwardly the front and back side plates 3| and 32 of the analyzing section of the machine. mountedfla sub-base 33 which supports a transverse wall 34 that combines with a similar wall 35 supported upon the base 30 to form a cham ber 38 for receiving and stacking cards after their analysis. Said wall 35 separates the analyzing section of ths machine from the tabulating section which is fully described in said parent application. Pivotally connected, at 38, to the upper portions of the side plates 3| and 32, are the two rails 39 of an auxiliary frame which further comprises the side plates 40 and 4i and Between said plates is- Divided and this application July 15,

a cover plate 42, said pivotal connection permitting said auxiliary frame and the entire mechanism supported thereby to be swung upwardly to a substantially vertical position, after effecting certain disconnections to be later described, in order that ready access may be had to the interior of the analyzing section in the event of a card jam, or for other purposes. The auxiliary frame is held in its horizontal operative position by removable dowel screws 43 extending through the rails 39 and into the side plates 3|, 32.

The main drive shaft 44 (Fig. 3) extends transversely of the machine directly above the base 30 and through the side plates 3|, 32, and is coupled, through a friction overload clutch conventionally shown at 55, to a pulley 46 at one end of the shaft which is connected to a driving motor (not shown) mounted conveniently below said base. A worm 48 on the shaft constantly drives a gear 453 surrounding the primary cam shaft 50 of the tabulating section of the machine and is adapted to be coupled to said shaft by a well known type of clutch mechanism, generally indicated at 5!, which is controlled by the intermittently operable print clutch solenoid 5| a to drive said shaft through one revolution each time the solenoid is energized and to stop said shaft at the end of its revolution if the solenoid is not re-energized. Said shaft 44 is also connected, by gearing 52, to a continuously operating shaft 53 which extends upwardly along the rear side plate 32 and adjacent wall 35, and constitutes the driving power for the card feeding and analyzing section of the machine. The upper end of shaft 53 is geared, at 54 (Fig. 2) to the horizontal shaft 55 supported in bearings on the outside of the plate 32 and having a worm 56 thereon which constantly drives a large gear 5'! (Fig. 3) which surrounds and is adapted to be coupled to one end of the transverse shaft 58 having bearings in the plates 3!, 32 and operable to control the various functions of said feeding and analyzing section. The coupling of said gear and shaft 58 is accomplished through a clutch mechanism 59 (Fig. 2), similar to the clutch 5|, controlled by the feed solenoid 59a which is intermittently energized and de-energized during each cycle of the machine as long as the feed and analysis of the cards is to continue, but which remains de-energized during a total-taking cycle so that said clutch will be effective to stop rotation of said shaft 53 to thereby discontinue operation of the feeding and analyzing mechanisms.

The switching unit 60, attached to the wall 32 and shown in dotted and full lines in Figs. 2 and 3 and which controls electrical circuits involved in various functions of the machine fully described in said parent application, is operated directly from the shaft 58 by a gear 6| which drives a cam shaft 62 in said unit 60. A plurality of cams generally indicated at 63 on said shaft 62 actuate individual switch arms 64 at-different predetermined intervals to control the micro 1 sioning devices I00, lll la on opposite sides of the machine. Similar devices Il, IOIa, maintain the Y upper rollerof the last pair adjacent the card switches conventionally shown at 65 and included in said electrical circuits.

The opposed walls of the card magazine 66, which latter is attached to the rails 39 and is thus movable with the auxiliary frame, are provided with vertical guide strips 67 (Fig; 4) that extend the entire height of said walls with their upper ends fixed to the top of the magazine and.

their lower ends free to be flexed by adjusting screws 68 whereby the cards may be properly centered in the magazine and allowance made for minute changes in the lengths of the cards caused by humidity variations.

Card feed mechanism Cards are fed from the magazine 66 (Fig. 4) by a reciprocating picker 69 operated from the crank I0 on the rock shaft II which is connected through the crank I2 (Fig. l) to a link 13 operated by the bell crank I4 having a follower T5 engaging with a cam 16 (Fig. 3) on the front end of the shaft 58. As successive cards leave the magazine (Fig. 4), they are carried along by pairs of feed rollers TI, first, into the card chamber I3 of a sensing station forming part of the analyzing mechanism and generally indicated at I9, then into the chamber 80 of the analyzing station 8| constituting the remainder of said 111G011 anism, and thence to the discharge or stacker chamber 36, the cards at each station being held stationary by the stop members 82 during the sensing and analyzing of said cards.

In the stacker chamber 36 there is disposed a vertically movable platform 83 carrying a plate 84 upon which cards are deposited from the adjacent rollers 11, and said platform is guided in its movements by a slot 85 formed in the wall 34. The platform 83 has depending therefrom an elongated rod 86 which is guided between pairs of rollers 81 carried in a bracket 88 secured to the wall 34, and which extends downwardly through the base members 33 and 30 and carries at its lower extremity a cross piece 89 to operate a switch contact 9| to release a normally closed micro switch 9 I a to thereby stop the feed of cards from the magazine 66 when the chamber 36 is full. The platform 83 is normally urged upwardlyby a pair of coil springs 92 fixed at their upper ends to the wall 34 and connected at their lower ends to the cross piece 89.

The lower rollers 11 of the two pair adjacent the magazine 66 are positively driven by worms 93 on the shaft 55 meshing with gears 94 on the shafts of said rollers, and the upper rollers of said pairs are geared to the lower rollers, and the upper rollers of said pairs are geared to the lower rollers and have adjustable tensioning devices 95 and 950. connected thereto. The next pair of rollers 'I'I are designed to have contact only with the edges of cards passing through the sensing station 19 and are geared to worms 96 on the shaft 55 and to worms 9! on the counter shaft 98 mounted on the side plate 3|, and the pair of lower rollers associated with the analyzing station BI are similarly geared to the two shaftsstacker chamber 36 operatively connected to the lower roller of said pair which is driven by worm I02 on'the shaft 55 and thus all sets of rollers Sensing and analyzing mechanism The vertically reciprocating pin boxes I03, I03a '(Fig. 4) of the sensing and analyzing stations 19,

8| are of identical construction with the exception, for control purposes, that the latter pin box mounts one more sensing pin I04 in each row individual to a card column than the box-I03. Said pin boxes are supported by castings I05 connected by cross plates I06 and have their lower extremities guided in standards I01. An eccentric I08 on the shaft 58 is coupled to the plates I06 so as to reciprocate the pin boxes in unison during rotation of said shaft. Stations I9, 8|, further comprise upper pin boxes I09, I09a supported in position above the boxes I03, I03a by therails 39 so as to be movable with the latter and carry with them the card stops 82 when the auxiliary frame of which the rails 39 form a part is swung to open position wherein it will now be apparent that the rollers I1 and the card chambers I8, will be fully exposed so that easy access may be had thereto in case of repair or a card jam. Rows of pins IIO, III, equal to the number of columns in the cards, are mounted in the upper pin boxes I09, I09a, and are vertically aligned with the respective rows of pins I04 in the lower boxes. In addition, the pin box I09a has, in each row of pins III, a control pin H2 adapted to be operated by the additional pin I,04 inthe corresponding row of the associated pin box I03a, and said pin H2 is provided with an extension II3 utilized in connection with the control or X position at the head of each card column. ,Lock plates H4 in the two upper pin. boxes I 09, I09a are provided for each row of pins IIO, III, IIZ to momentarily hold those pins elevated, during the sensing and analyzing operations, which have been raised by the sensing of holesin a card by pins I04 in the lower pin boxes. The plates II4 are under the combined control of cross bails II5, each common to the plates in one of the upper pin boxes, and of in-' dividual spring urged bell cranks II6 each of which tends to move its plate I I4 to the right, as- Viewed in Fig. 4. The bails I I5 are carried by two bars Ill (Fig. 3) on opposite sides of the boxesl09, I 09a and these bars are actuated, immediate-- ly following the elevation of the pins IIO, III, by cranks H8 at opposite ends of a rock shaft II9 supported in the rails 39. Such actuation moves the bails to the right and thus permits the bell' cranks I I6 to shift the lock plates into locking position relative to the elevated pins IIO, II I. Said lock plates remain in operative position until the bails II5 are returned to restore said plates and thereby release the elevated pins following thej performance of their functions. The shaft H9 carries a crank I20 (Fig. 1) to which is detachably' connected a link I2I joined to a lever I22 (Fig. 3)

operated by a cam I23 on the shaft 58 to control the reciprocating movements of the bails I I5.

The card stops 82 are controlled from a cam I24 on the shaft 58 engaging a lever I25 which is directly in front of the lever I22, as seen in Fig. 1. A link I26 detachably connects the lever I25 to a rock shaft I21 to which are joined, by cranks, adjacent ends of two bars I28 (Figs. 3 and 4;) arranged alongside of the bars Ill, and the other ends and intermediate portions of said bars I20 are diagonally slotted at I29 to receive pins I30 carried by the slidable plate I3I on each pin box I09, I-9a and which carries a stop 82 associated with the adjacent pin box. Through this linkage, cam I24 operates the two bars I28 to simultaneously raise the card stops 82 upon retraction of the sensing pins I04 so that the cards temporarily held in the chambers I8 and 80 will be discharged therefrom by the continuously driven rollers 11, after which the stops are again lowered by the cam I24 to stop the succeeding cards enterin said chambers during the next cycle of operation.

After the motor has been energized, the machine operation is initiated by depressing the start key I3Ia (Fig. l) to thereby energize the feed clutch solenoid 59a which then permits the clutch 59 to become effective to drive the shaft 58. Said solenoid is de-energized during each revolution of said shaft but is re-energized before deolutching of the shaft can take place, as long as the feed of the cards is to continue. The key I3Ia is held depressed to maintain the starting circuit closed for two machine cycles to thus allow two cards to be fed from the magazine and to the stations I9, 8I, which would not otherwise occur because of card sensing devices at said stations that operate, in the absence of a card at either station, to stop the machine. Each of said devices (Figs. 3 and 7) includes a card sensing pin I3Ib carried by the movable pin box at its station and adapted to sense the presence or absence of a card thereat. Said pin I3Ib is supported by a plunger I3Ic movable in the casing I05 and which is normally urged upwardly by the coil spring I3Id, and the lower end of said plunger is positioned directly over and movable relative to the free end of a contact arm I3Ie rockingly supported in the block I3If carried by a multi-contact microswitch I3Ig. When pin I3Ib does not engage a card, the plunger I3Ic moves upwardly and out of engagement with the arm I3Ie and the various contacts of the associated microswitch I3Iy assume their normal position. As each plunger I3lc moves 7 downwardly, its collar I3I:i will contact and flex the arm I3Ie, thus reversing the normal condition of the various switch contacts and if, upon the next upward movement of said plunger, the pin I3I b engages a card II8 as shown in Fig. 7., said upward movement of the plunger will be arrested with its collar still contacting the arm I3Ie to retain the latter in its operated position. Therefore, the contacts controlled by said arm will be held in their reversed positions as long as a pin is in sensing position, and as the pin box casting I05 again recedes, the plate I3Ih thereon will contact the collar I3I7' to lower the plunger I3 lo and its pin I3Ib sufiiciently to allow the card just sensed to be fed from the card chamber.

The micro switches I3Ig at the two stations are in series with an energizing circuit (not shown) that controls the print clutch solenoid 5Ia; hence, cards must be present at both stations 19,, BI and both said switches must be closed 'before the start key is released in order that s'aid solenoid 5Ia may be energized to couple the shafts 44 and 50 and thereby eifect operation of the printing and accumulating section of the machine. Also, as will later appear in detail, with the first card of a run at station I9 but none at station 8I, a non-comparing condition will exist which, when sensed during the first cycle, will cause the group control mechanism to operate and thus prepare the machine for a total-taking operation on the next cycle by preventing the feed solenoid from energizing to thereby stop further feeding operation and by causing the print solenoid 5Ia to be energized to drive the shaft 50. During said first cycle and with the print clutch solenoid 5la de-energized, the print section of the machine remains inoperative since the shaft 50 will not yet be coupled to the shaft 44, but when a change of designation takes place and the shaft 50 is driven through the next cycle, it will raise the type bars of the machine to their extreme or blank positions so that no printing will result. Subsequently, the machine enters its third cycle with cards at both stations 79, 8| and normal operation then proceeds in a manner which will be understood from the following description.

Scanning device for upper pin homes This device is used for the purpose of scanning the pins H0 in the upper pin .box- I09 of the sensing station I9 at which cards are compared with those at station 8I to sense a change of designation and to initiate the operation of the group control mechanism in case punched code designations in the cards at the two stations do not compare, as will be later described in detail.

The frame 2II of the device, which is mounted over the pin boxes I09, I09a, is reciprocated intimed relation to the analysis and sensing of the cards at the two stations and its movement is under the control of two pairs of complementary cams 2I2 (Figs. 1, 2 and 3) at opposite ends of the shaft 58. On opposite sides of the machine and on opposed sides of each pair of cams there are fulcrumed at 2I3, 2| 3a and 2M, 2'I4a, to each of the side plates 3| and 32, the pairs of short and long levers 2 I5, 2I6 and 2I5a, 2I6a connected by the cross links 2II and 2IIa. The pairs of levers 2I5, 2I5a on opposite sides of='the machine carry rollers 2I8, 2I8a, each engaging with one of the adjacent cams 2I2, while rollers 2I9, 2I9a on the pairs of levers 2I6, 2I6a engage the adjacent complementary cams so that as the two sets of cams are rotated by the shaft 58 the described leverage will oscillate about the fulcrums 2I3, 2I3a and 2M, 2I4a. The upper ends of the two pairs of levers 2I6, 2I6a on opposite sides of the machine are detachably and pivotally connected to links 220, 22011 which join saidlevers to the extensions 22I on opposite sides of the scanning frame 2H so as to reciprocate the same.

The elevation and locking of pins H0 and III in the units I9, M, as a result of the operative strokes of the pin boxes I3, !03a, is immediately followed by the right hand movement, as viewed in Fig. 4, of the scanning device which now functions to sense any locked pins IIO, III and to transmit data represented by the latter pins through an analyzer controlled mechanism. This sensing is accomplished, with respect to the pins IIO, by operating pawls 222, one for each row of pins, pivotally mounted in the scanning frame 2H for operation in connection with the automatic group control mechanism. Similar pawls 223 also forming part of said analyzer controlled mechanism and supported in the frame 2II move over the pins III in the pin box I99a and wherever a pawl encounters an elevated pin, said pawl will be raised to engage the corresponding tooth of its associated slide 225 which, until such engagement, remains stationary with respect to the frame 2. However, when said slide is so engaged, it will move with the scanning frame to the end of its stroke and, in so doing, its initial movement will rock the associated lever 226 due to the recess 22! in the upper edge of the slide in which one end of said lever normally rests. This movement of the lever will rock the bell crank I44 individual thereto so as to operate the associated actuating bar I36 which forms part of the analyzer controlled mechanism for the upper transfer unit described in said parent application. After all the pins III have been scanned and the data .represented thereby has been transmitted to said transfer unit by the various operated bars I36, the scanning frame returns to its starting position and, during this secondary stroke, restores the operated slides 225, and also the slides 239 later to be described, by engagement of portions of the frame with the lips 228 of said slides, whereupon all operated levers 226 and bell cranks I44 will also be restored by a subsequent action which takes place in the control of the bars I36.

When an X hole is sensed at the station Si by the additional pin I04 in the pin box I03a, its corresponding control pin H2 is elevated, but this pin being shorter than the pins I I I, will not be contacted by the pawl 223 thereabove. The raising of said pin II2 causes its extension II3 to engage the adjacent end of its associated lever I45 pivotally mounted in the swinging bail 229 so that the opposite end of said lever will align itself with the associated actuating bar I31 of the analyzer controlled mechanism for the lower transfer unit also described in said parent application, whereupon the bail 229 is swung to the left as viewed in Fig. 4, to cause any of the operated levers I45 to impart linear movement to the respective bars I31 with which they are aligned while any unactuated levers I45 will pass over their bars. This action takes place before the scanning device starts its primary movement so as to enable any operated bar I31 to effect the suppression of an associated type bar in the print section of the machine (not shown) before it can start its upward travel in timed relation to the movement of the scanning device, Or to perform other functions which are controlled by the appearance of an X hole.

The bail 229 common to all the levers I45 is rockingly supported on the shaft 230 extending between the rails 39 and said shaft is controlled by a cam 23I (Fig. 3) mounted on the shaft 58. Said cam is engaged by one end of the bell crank 232 (Fig. 1) pivoted on the side plate 3|, to the other end of which is connected the lower extremity of the link 233; and the upper end of said link is detachably connected to a crank 234 carried by said rock shaft 239. After its operation by the cam 23I, the bail 229 and the associated parts are restored by the spring 235 connected to the bell crank 232.

Designation Change Sensing Mechanism Inthe present machine, this is accomplished by the mechanical comparison of cards at the sensing and analyzing stations 19 and BI, and when said cards do not compare, indicating a change of designation, the operation of the analyzing section of the machine, including the card feed, is stopped for one cycle, totals are taken during said cycle and, at the conclusion thereof, the card feed and analyzing operations are automatically resumed. Provision is made for the automatic taking of the two classes of sub-totals, which may be designated A and B, from different fields of a card; while the initiation of the taking of a grand total is accomplished by a manual opera tion such as the pressin of a key 236 (Figs. 1 and 6) to re-start the machine after it has been automatically stopped at the conclusion of a card run. The remaining key and switches adjacent the key 236 and not specifically referred to herein are employed to control other operations of the machine which are not concerned with the change of designation control of the present invention. The taking of sub-totals A and B, in response to a change of designation, is initiated from the micro-switches (Figs. 2 and 6) generally indicated by the numerals 231 and 233, respectively, and the automatic control of these switche will now be described.

As briefly mentioned hereinbefore, any elevated and locked pin III] in each row of pins will be projected into the path of the pawl 222 individual to said row, causing said pawl to be elevated, as described in connection with the pawls 223, as the scanning frame 2| I progresses through its primary movement. Associated with each pawl 222 and supported thereabove by said scanning frame is a slide 239 identical to the slides 225 and controlled in the same manner so as to be moved with said frame when its raised pawl 222 engages a tooth 24I] corersponding to the pin III) which has been elevated. Movement of said slide 239 with the frame 2II disengages one end of a lever 24I from a recess 242 in the upper edge of the slide and thus causes a slight upward swinging movement of said lever, the purpose of which will later appear. With this arrangement it becomes apparent that if corresponding teeth 224 and 240 in the respective slides 225 and 239 are engaged by the associated operating pawls 223 and 222, indicating a similarity in the group designation of the cards then at the two stations 19,-8I, both said slides will be moved simultaneously by their pawls to likewise rock the levers 226 and 24I, with the result that the group control mechanism, presently to be described, will not become effective to stop the card feed and initiate a totalizing operation at the conclusion of the analyzing cycle and with the further result that the lever 226 will perform its previously described function.

However, if two cards at the sensing and analyzing stations do not compare, then one or the other slide 225 or 239, depending upon the relative positions of the non-corresponding pins III, III), will be first engaged and moved by its pawl, followed by the secondary engagement and movement of the other slide. This differential in movement of the two slides results inthe operation of one or the other of the switches 231 or 238 depending upon a prearranged set-up made in the group control mechanism in which set-up one field of each card, together with the associated pairs of slides 225, 239, is assigned for taking an A total and a different field is allotted t the B total.

escapes Each pair 01' levers 226, 24] when rocked either simultaneously or successively, operates a pair of bell cranks 243 and 244, respectively, and the latter elements carry spring-urged pawls 245 and 246 with which is associated an analyzer controlled slide 241 that responds to the operation ofsaid pawls with primary and secondary movements in the same direction,'only the secondary movement occurring when there-is a change of designation. At each end of said slide the same is provided in its lower edge with a pair of teeth 248, 249, the former of which are engaged by the pawls 245, 246 during the normal condition of the control mechanism, and also during the primary movement of the slide 241 if both said pawls are operated simultaneously. The upper edge of each slide is provided with elongated slots 250 and 25! with which are associated, respectively, the actuating member 252, 253, in the form of a pair of spring-urged levers that normally :assume the position shown in Fig. 4 in which their outer extremities are out of the slots 250, 2 5| Said levers are pivotally supported in rocking bails 254 and 255that are keyed'to the shafts 256 and 2 51 journaled in the side plates 40, 4|

(see also Fig. 2) and which carry the trip plates 258 and 259 of the respective switches 231, 238 so as to close the latter when said shafts are turned by a rocking movement of the bails 2.54, 255.

- To establish a predetermined set-up in the control mechanism with respect to two or more difierent fields of the cards which are allotted for A and B totals, there is provided a selector device generally indicated at 260 and mounted directly beneath the top plate 42 and partially encased by an auxiliary plate 26l, said device comprises a plurality of slides 262 arranged side by side across the machine and each being individual to one of the card columns. Each slide has a key 263 which extends upwardly through a slot in the plate 42 whereby the key may be adjusted from the neutral position of Fig. 4 to the left or right depending upon whether the card column to which the slide is individual is in a field from which A or B totals, respectively, are to be taken. A spring 264 urges the slide 262 downwardly against the plate 26| which is slotted to receive a guide lug 265 and a projection 266 both on the lower edge of the slide. The projection 266 engages in a recess in the rocker member 261 individual to said slide and mounted, with other similar members, for rocking movement of the common shaft 268. The two lower extremities of the rocker member 261 engage the inner adjacent ends of the associated levers 252 and 253, and control the positions of said levers with respect to the slots 25!] and 25l in the slide 241.

In adjusting the selector device preliminary to a machine operation, if a slide .241 assigned to any column of a card is not to be involved in the taking of an A or B total, its associated slide 262 remains in, or is adjusted to, the neutral position so that the rocker member 261 and the levers 252, 253 will assume the position of Fig. 4 wherein said levers will be unaffected by either the primary or secondary movements of the slide 241, which movements are under the influence of th Slides 25, .239-

To assign said slide 241 for the taking of an A total, the corresponding key 263 isshifted to the left position, thereby rocking the member 261 counterclockwise to depress the inner end of the lever 252 and release the corresponding end of the lever 253 whose outer end then enters the right hand extremity of the slot 25! in the slide 241. From this, it will be apparent that an adjustment to the right hand position of the key 263 associated with another slide 241 assigned to B total-taking, will effect a reversal of the operation just described so that the outer end of the lever 252 will be positioned in the right hand extremity of the slot 250 of said slide.

' A suming now that two cards at the stations 19, 8!, have the same group designations, the pawls 222, 223 will be raised simultaneously by the elevated pins H6, III to engage corresponding teeth in the two slides 225, 239, with the result that said slides will be moved from their I normal positions at the same time and thus simultaneously rock the bell cranks 243, 244. This action causes the pawls 245, 246 to impart only the primary movement to the slide 241 against the tension of its return spring 269. With the outer end of one or the other levers 252, 253 in the right hand extremity of its associated 'slot 250, or 25l, the latter are of such length that, at the conclusion of said primary movement, the left hand extremities of said slots will only reach, but will not move, the levers 252 or 253 and, therefore, neither of the bails 254, 255 will be rocked to turn their respective shafts 256, 251 to close the associated switches.

Should non-corresponding pins H0, Ill be elevated, indicating a change of designation of the cards, either one or the other of the pawls 222, 223 will be raised first to operate its slide 239 or 225, with the result that one of the bell cranks 243, 244 will be actuated to cause its pawl 245 or 246 to move the slide 241 through its primary movement. The pawl not actuated will then engage the associated second tooth 249 of said slide preparatory to moving the latter through its secondary movement when the bell crank on which the latter pawl is mounted is actuated by the lifting of the other pawl 222 or 223 when it contacts with one of the pins I H] or II I following the operation of the other of said latter pawls. The secondary movement of the slide 241 will actuate the lever 253 or 252, depending upon whether an A or B total is to be taken, and the actuation of said lever will swing its bail so as to turn the proper shaft to close the switch 231 or 238 to thereby stop the feed section of the machine for one cycle, by maintaining the solenoid 59a de-energized, and initiate a total-taking operation. Upon conclusion of the described operation and while the scanning frame 2| I is being restored to its startin position, the restoring bail 216 is reciprocated by a crank 21! on the shaft 212 to trip the pawls 245, 246 so as to disengage them from the teeth of the slide 241 which then restores to its normal position under the influence of its spring 269. one end of the shaft 212 (Fig. 2) is joined, by a crank 213, to the upper end of a link 214, the lower end of which is connected to a crank 215 mounted on a shaft 216 which also carries a crank 211 controlled by a cam 218 (Fig. 3) on the shaft 58 so that the shaft 212 will be rocked to reciprocate the bail 210 in timed relation with the movement of the scanning frame 2| i.

It will now be apparent that the taking of an A or B total will be controlled from either the sensing station 19 or the analyzing station 8!, depending upon the relative positions of the elevated pin at said stations and also upon the pre-selection of either of the levers 252 or 253 for operative association with the slide 241.
